underlying these raw materials are volatile and have fluctuated significantly in recent years and in the future may contribute to fluctuations in our results of operations. The ability to hedge these commodity prices is limited.
We are exposed to risks of changes in shipping and freight costs, including container and other third party fees associated with the transportation of our products. Shipping and freight costs have fluctuated significantly in recent years and in the future may contribute to changes in our results of operations.
In the normal course of business, we are exposed to foreign currency translation and transaction risks. Our business transactions outside of the United States are denominated in the euro, Malaysian ringgit, Mexican peso, Thai baht and other currencies. We may use foreign currency forwards, swaps and options, where possible, to manage our risk related to certain foreign currency fluctuations.
We are exposed to market risk from changes in interest rates related to our borrowing under our Revolving Credit Agreement and Receivables Financing Agreement. E xcluding deferred financing costs and third party fees, we had $500 million in borrowings under our Term Loan A, $600 million in borrowings under our Term Loan B, $11.7 million in borrowings under our revolving credit facility, $230 million in borrowings under our Receivables Financing Agreement and $28.0 million in letters of credit under the Revolving Credit Agreement at March 31, 2022. After considering the effects of an interest rate swap agreement entered into during April 2022, we estimate an increase in interest rates of 100 basis points would result in a potential reduction in future pre-tax earnings of approximately $9.4 million per year based on our borrowings outstanding at March 31, 2022.
Due to the nature and pricing of our Products & Healthcare Services segment distribution services, we are exposed to potential volatility in fuel prices. Our strategies for helping to mitigate our exposure to changing domestic fuel prices have included using trucks with improved fuel efficiency. We benchmark our domestic diesel fuel purchase prices against the U.S. Weekly Retail On-Highway Diesel Prices (benchmark) as quoted by the U.S. Energy Information Administration. The benchmark averaged $4.30 and $2.91 per gallon in the first three months of 2022 and 2021. Based on our fuel consumption in the first three months of 2022, we estimate that every 10 cents per gallon increase in the benchmark would directly reduce our Products & Healthcare Services segment operating income by approximately $0.2 million on an annualized basis. We are also indirectly exposed to increased shipping and freight costs, including container and other third party fees associated with the transportation of our products due to changes in fuel prices. Changes in fuel prices have contributed to significant shipping and freight costs in recent years and in the future may contribute to changes in our results of operations.
